HiLo Game In Java - User Can Choose Up To 3 Different Levels With 3 Methods
Apr 25, 2014
I will try to explain what i want to code , a HiLo game where the user can choose up to 3 different levels(1-10, 1-100, 1-1000) with these 3 methods
public static void main(String[] args) {...}
public static int playGame(int maxNumber) {...}
public static void giveResponse(int answer, int guess) {...}
with no Random , i will use the:
int number = (int)(Math.random() * max) +1; to generate numbers
I have tried so many times , but i don't get it ....
My code so far :
import java.util.Scanner;
public class HL{
public static void main(String[] args ){
Scanner s = new Scanner(System.in);
[Code] ....

I am a beginning programmer and was learning how to make an XML. It was for a simple game and only needs to hold the highscores of three different levels. Here is what I coded:
try {
OutputStream fout= new FileOutputStream("highScores.xml");
OutputStream bout= new BufferedOutputStream(fout);
OutputStreamWriter out = new OutputStreamWriter(bout, "8859_1");
[code]....
My issue is that I run this code every time I create the program and the scores are reset to 0. How can I make a small change so that I only run this block of code and create the XML the first time the program is run?

I am using eclipse for this project. Every time I run this program the choose method will always choose 0. Ignore the Sleep.sleep() method, there is another class in the program that performs it.
import java.util.Scanner;
public class gamestart {
public static int num;
public static String name;
public static String diff;
public static String choice;
[Code] ....

I am trying to create a slightly modified cash register. The user will enter the amount of the item, the payment received, calculate the change/refund, and then allow the user to choose the preferred bills.
import java.util.Scanner;
public class Register {
private static Scanner input;
public static void main(String[] args) {
input = new Scanner(System.in);
System.out.println("*****CASH REGISTER*****" );
System.out.print("Item Amount: " );
int amount = input.nextInt();
[Code] ....
I will try to clarify the code, to make things a little easier to interpret. in the refund method, I have set up a 2-d array to exist and function as an excel sheet. The refund amount is passed to the method and compared to each bill of the array. Once the refund is determined to be greater than a bill, the user is prompted to enter the preferred bill type. This is where my problem is...I would like the program to then calculate the number of bills and keep a tally of those bills in the 2nd column and then determine the new refund amount at which point the user will be prompted again to determine the desired bill.
Then print out the array of bills that are not equal to 0.

I have a question about a method I have. In my game, I had a move method to move my player left and right, and originally this method was huge, as it also took care checking collisions and a few other things. I broke it up a bit and put the collisions in their own methods and call them from again another method... Here is an extract which I hope illustrates my point:
private static final double MOVE_SPEED = 0.2;
private static final double MAX_MOVE_SPEED = 3.5;
private static final double STOP_SPEED = 0.18;
private double xPos;
private double yPos;
[Code] .....
Something I thought might be a good idea is to check the direction collision when im doing the calculations for that direction:
if(moveLeft) {
dx -= MOVE_SPEED;
(dx < -MAX_MOVE_SPEED) {
dx = -MAX_MOVE_SPEED;
}
checkLeft();
}
But then I would also need to check it when I'm slowing down the left movement:
if(dx < 0.0) {
dx += STOP_SPEED;
if(dx > 0.0) {
dx = 0.0;
}
checkLeft();
}
Then I thought instead i can check it after both of these steps:
if(moveLeft || dx < 0.0) {
checkLeft();
}
I guess my question is quite general: How much is acceptable to break up a method? How many chains of method calls is acceptable? Is it ok to call the same method from different nearby places?

I have several Windows 7 Enterprise machines that have already been deployed via image and need to lower the security settings for use on internal web based applications.
Is there an easy way to manipulate the configuration (a file) so that I may simply make the changes by overwriting the current configuration settings instead of, having to go to each device, opening the Java console, and changing the security settings that way?
I have attempted to login as the machine administration, make the changes on the Java console with the hopes this configuration would have migrated to all user profiles that log into the PC. Is there a "public profile" configuration file I can change and if so, what should I do.

I'm trying to build a program that will output what will ultimately look like a simple mario level turned on its side. As part of my output I need the user to define what mario looks like. I do this using Scanner and save the input to String mario. When I try to use that variable in another method it gives me troubles.
import java.util.Scanner;
public class Mario2
{
public static void mario() {
//user defines mario
String mario = ">->O";
Scanner keys = new Scanner(System.in);
System.out.println("What does mario look like?");
mario = keys.next();
System.out.println("Mario now looks like: " + mario);

I'm making a "very" basic blackjack game, and I'm stuck on how to get a user response to hit and stick game play.
import java.util.Random;
import java.util.Scanner;
class blackjack {
public static void main ( String[] args ) {
Random r = new Random();
Scanner keyboard = new Scanner(System.in);
String money;
String name;

I know people will want me to tidy it up, or do it "their" way, but honestly I just need method of getting the user to press h or s and have the program continue under it's own steam.

I am making a very simple 2D array game where the player is asked what size they would like the game board to be. After entering, it displays the board and the player 'P' starts at index [0][0]. After that, they are asked for an action, which can be "up", "down", "left", "right", or "exit". I will be including some extra later (like a treasure at the end, or random obstacles), but for now this is what the game consists of.
I was instructed to "do nothing" when/if the player attempts to go out of bounds. I am trying to simply print an error, such as "Out of bounds! Try again.", then prompt the player again for an action. I even tried to make a boolean method to catch it, but to no avail.
I don't want the exception to occur at all. I just simply want the error message to print to the player and ask for another action. I would prefer not to use try/catch, or try/catch/finally since I already tried that and it still gave the exception error.This program consists of two classes. I will show the class containing the main first, then the client-server type class second.
import java.util.Scanner;
public class Driver {
public static void main(String[] args) {
World world = new World();
boolean keepPlaying;
keepPlaying = true;
boolean isOutOfBounds;
isOutOfBounds = false;
int height = 0;
int width = 0;
int x = 0;
int y = 0;

I am creating a hangman code. So the game i am creating is 2 player, first player enters the word and second player guesses. i made the code but i don't know how to restrict the first player from adding random characters into the secret word because for my project the word can only contain letters. so i need making the code so the player 1 can only enter letters.
My code is below:
/**
* Auto Generated Java Class.
*/
import java.util.Scanner;
public class Hangman {
public static void main(String[] args) {
Scanner input= new Scanner(System.in);
String player1,player2;
int wrongguessamount = 0; //keeps the count of the amount of wrong guesses
int correctguessamount = 0; //keeps count of the amount of correct guesses
int maxincorrect=6;//makes sure the user cant guess more than 6 times

I have small project to be implemented in Java, which, expected the management of a parking.
The project has a class abstract Vehicle, whence derive three classes: Car, Motorcycle, Heavy Vehicles; the cost estimated time for the 3 types of vehicles are: 2€ for Cars, 1€ for Motorcycle and 5€ for H.V.
In addition, in class Ticket will be stored the arrival time of the customer and the characteristics of his vehicle.
Finally, in the class Parking(which provides 80 places available), here it should be added the various types of vehicles.
Now, I though of using an Collection, as Set.. So that they can not, two Vheicle with same license plate.

My assignment is to create a hangman game. One of my first difficulties with it is how to scan the string for an input supplied by the user.
Here is my method:
//Guesses that character c is in the secret word.
//Updates all instance variables accordingly,
//and returns true if c is present in the secret word.
public boolean guessCharacter(char c){

The problem occurs after the user inputs the guess.... it either runs the for loop if guess = numtoguess and reveals the answer even if the user input is wrong.... or it always runs the first if statement in the while loop if guess!= to numtoguess... heres the code
public static void main(String[] args) {
String[] Answers = {"yes", "Yes", "No", "no"};
String Name = JOptionPane.showInputDialog(null, "Hello, What is your name?","Random Game", JOptionPane.QUESTION_MESSAGE);
String UI = JOptionPane.showInputDialog(null, Name + " do you want to play a game", "Random Game", JOptionPane.QUESTION_MESSAGE);

I recently wrote a simple recursive program that chooses K objects out of N (I was asked to use the variables N choose the R, however) total objects. Here is the code:
int n = 0;
int r = 0;
//the total number of objects defaults to 0
String nChoice = JOptionPane.showInputDialog(null, "How many objects are there to choose from?");
String rChoice = JOptionPane.showInputDialog(null, "How many object are to be chosen from this group?");
try {
n = Integer.parseInt(nChoice);
[Code] ....
It works fine, however in my class we were given two different formula to implement into our code. I used the one above, obviously. However, the second formula we were given was:
C(n,R) = n!
-------(R!(n-R)!)
I had to get the spacing right.
How do I read this formula? How could it be implemented? What are the benefits (if there are any) from using one method over the other? Which method of calculating N choose K (or, in my case, N choose R) would be more widely accepted?

When I run my program and choose option 2 to get contact details I am expecting it to display as follows (First Name, Last Name): Contacts how have been entered:
0) John Doe
1) George Smith
2) Nancy Davis
Please enter the number corresponding to the contact you would like to view:
Instead for a personal contact it is displaying as follows:Contacts who have been entered:
0) Doe 1 F St. (last name, address)
Please enter the number corresponding to the contact you would like to view:
Instead for a business contact it is displaying as follows:Contacts who have been entered:
0) 1 F St. jd@gmail.com (address, email)
Please enter the number corresponding to the contact you would like to view:
Then when I enter the number to display the contact for personal it is returning me only first name and business is only returning me first and last name. It should be returning the full contact info that was put in during the add contact step. I thought I programmed everything properly but it isn't displaying what I want to seeMy code is listed below.

Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

Write a program using switch statement to allow users to choose an item of a menu. For example, the menu looks like the following.
File menu
1. Open
2. Close
3. Save
4. Exit
Enter your choice:
If you type 1, then your program should print out "Open is selected" (double quotes not included).
Notice:
(1) Using Scanner to get user choice;
(2) If the number user input is not in {1,2,3,4}, your program should let user know that.
Here's what I have:
public static void main (String[] args) {
int user = 1
switch (1) {
case value: 1
System.out.println ("Open is selected");
